When i have this material what texture i must apply to the mesh?
THere are 2 texture type:

F16-LAK_JPG-sampler
and
F16-RTAI_JPG-sampler

one for the diffuse and one for the reflective .
Thanks

Most of the time, you should use F16-RTAI_JPG-sampler, the one from <diffuse> element.

Effect with <profile_COMMON> is confusing when it comes to transparency, blending, and multi-texturing. You can see different importer/exporter use different meaning.

Correctly me if I am wrong.
texture from <ambient> could means ambient occlusion map.
texture from <specular> could means specular map.
texture from <reflective> and <refractive> could means cubemap/spheremap/etc.

Feeling Software extensions for texture are documented on the wiki here:
